It is a few years since I worked on three bearing engines, but I have an open ended spanner that I shortened to about 2 inches long that could be accommodated in the crank case. I think 3/8 BSF [ same size as centre bearing pipe nut]. I then either levered this short spanner or tapped it using a brass drift
to slacken the nut. I am assuming you are refering to the rear crank case end of the pipe.
